Definitions

  • the present invention relates to an ion exchange device for water purification or for improving the water quality, preferably for reducing the nitrite and / or nitrate content, consisting of at least one exchange container with a basic anion exchanger in chloride and / or sulfate form arranged therein.
  • the invention further relates to a method and the use of the ion exchange device for drinking water extraction.
  • the ion exchange device contains at least one additional anion exchange layer in hydroxyl form.
  • the first method is unusable for producing limited quantities of drinking water for household purposes in simple devices.
  • the second method has the following disadvantage: If water, which contains different anions such as chlorides, sulfates, nitrates, carbonates and phosphates, by the known anion exchange resins is directed, the sorption of the individual anions is different in accordance with the ion affinity of the exchange resin, and a filtrate is obtained with a completely different content of anion components
  • the aim is only to remove or reduce the nitrate ion content, while at the same time the concentration of the other anions in the original water should remain largely unchanged or should only be changed to a certain extent.
  • Some known anion exchange resins which have a particular affinity for nitrate ions, nevertheless change the chloride, sulfate and carbonate concentrations to a great extent.
  • the present invention further relates to a method for producing the ion exchange device for water purification or for improving the water quality, preferably for reducing the nitrite and / or nitrate content, consisting of at least one exchange container with a basic anion exchanger contained therein Chloride and / or sulfate form.
  • Nitrites, chlorinated hydrocarbons and pesticides are also reduced.
  • the basic anion exchange layer in sulfate form is shown under GS
  • the basic anion exchange layer in chloride form is shown under GCl, it being indicated whether the anion exchange layers are strongly basic (strong) or weakly basic (weak).
  • the basic anion exchange layer is given in hydroxyl form under OH and the activated carbon layer under F.
